Description

The present invention relates to a pinbone removal apparatus that efficiently removes pinbone remaining in a fillet obtained by dropping three fish bodies such as autumn salmon and trout.

  Fish bodies such as autumn salmon and trout have many elongated small bones called pinbones (35 to 38) protruding laterally from both sides of the middle bone, and when this fish body is lowered three times by a fillet machine The pinbone remains in a line in the length direction on the fillet side, and is not perfect as watered fish meat. If eaten, the pinbone may be stabbed, so it is difficult to adopt as food. Therefore, for example, as shown in Patent Document 1, an apparatus for automatically extracting a pin bone from a fillet has been developed.

  This device is capable of moving up and down with a certain interval in the conveying direction between a pressing roller having a large number of meshes and a drawing roller having a large number of pin bone insertion holes above the conveying direction of the conveyor that conveys the fillet. And the tip of the abutting member is disposed along the lower circumference of the drawing roller so as to face the conveying direction of the conveyor. First, the surface of the fillet conveyed by the conveyor is The tip end of the pin bone is lifted from the surface of the fillet by being pressed by the pressing roller, and then when being transported to the drawing roller side, the protruding tip portion of the pin bone is inserted into the pin bone insertion hole of the drawing roller and The pin bone is clamped between the tip of the contact member and the hole wall of the insertion hole, and the pin bone is extracted from the fillet according to the conveyance of the fillet.

  However, according to the pin bone removing device from the fillet, the pin bone is lifted by pressing the fillet with the pressing roller and then conveyed to the drawing roller side. Even if it floats up, if it passes through the pressing roller, the pressing force from above is released and the fillet is restored to its original thickness. At the same time, the pin bone immediately settles in the fillet and is pinched by the drawing roller and the contact member. There will be a situation where the pinbone is not pulled out without passing through.

  Furthermore, since the portion having the pin bone of the fillet is directly pressed from above by the pressing roller, the pin bone may be pressed by the pressing roller and may not protrude from the surface of the fillet. As the roller rotates, it is pushed down by the yarn forming the mesh, and it may be in contact with the surface of the fillet and cannot be pulled out by the drawing roller and the contact member. There was a problem that the number of wires increased and the efficiency deteriorated.

  In addition, since the pressing roller and the drawing roller are configured to be pressed against the surface of the fillet by the spring force, there is a problem that the contact pressure with the fillet is increased, the body is broken, the body is broken, and the yield is reduced. It was.

The present invention has been made in view of such problems, and the object of the present invention is to project the tip of the pinbone from the surface of the fillet without directly pressing the pinbone remaining on the fillet. It is an object of the present invention to provide a fillet pin bone removing device capable of efficiently and smoothly performing pin bone extraction processing while maintaining a protruding state.

Yes.

In the fillet pinbone removing apparatus configured as described above, the invention according to claim 2 has a certain interval in the width direction of the conveyor above the fillet conveying surface of the conveyor that conveys the fillet from the front side to the rear side. The vertical frame bodies on both sides are arranged so that the height from the fillet conveying surface can be adjusted and can be moved up and down, and the both ends of the rotating shaft that is rotated by the motor are attached to the lower ends of the front support frames in these vertical frame bodies. The rotating gear body is fixed to the central portion in the length direction of the rotating shaft while being rotatably supported, and both end portions of the claw member mounting shaft are attached to the lower end portions of the rear supporting frames in the both side vertical frame bodies. the by rotatably is supported Yes to protrude the pawl member obliquely downward toward the front in a central portion in the length direction of the mounting shaft, further, the lever portion at both ends of the pawl member mounting shaft Projecting from the pawl member mounted shaft via a lever member spring between the upper end of the rear portion and the rear support frame of the lever member is interposed by the elastic force of the spring together are fixed to the front end of the The tip of the claw member is pressed against the lower peripheral portion of the rotating gear body.

According to a third aspect of the present invention, there is provided the fillet pinbone removing apparatus according to the first and second aspects of the present invention, wherein both end portions of the fixed shaft are provided at intermediate portions in the height direction of the front support frame in the both side vertical frame bodies. A structure in which a support plate is fixed to the fixed shaft so that the height can be adjusted in the vertical direction, and a presser member is attached to the lower end of the support plate at a certain distance from side to side. have.

According to the first aspect of the present invention, because it is configured so as to press the portions on both sides of the pin bone existing in the fillet by the pair of left and right pressing members disposed above the fillet transport surface of the conveyor, Without directly pressing the fillet part where the pin bone exists, the fillet part on both sides is compressed by these holding members and the fillet part between them is also indirectly compressed, so that the tip part of the pin bone can be easily and reliably removed from the fillet surface. Furthermore, since the fillet conveying surface of the conveyor is gradually inclined downwardly toward the lower side of the rotating gear body that pulls out the pin bone, and is running parallel to the lower surface of the pressing member from the inclined upper end. The both sides of the surface of the fillet are in contact with the lower surface of the horizontal pressing surface of the presser member and are transported rearward to face the horizontal direction from the inclined upper end of the conveyor. Fillet tip portion of the refracted and pin bones, which is provided in the fillet until it can be erected from the surface of the fillet in the mountain shape when changing, therefore, the protruding tip portion of the pin bones by the right and left pressing member from the fillet surface The pin bone can be extracted smoothly and efficiently by the rotating gear body while the maintained state is reliably maintained.

  Further, the projecting proximal end of the pin bone projecting from the surface of the fillet is sequentially brought into contact with and received by the tip of the claw member according to the conveyance of the fillet by the conveyor, and the lower peripheral part is in contact with the tip of the claw member. Since the rotating gear body is configured to be pulled out by pinching the pinbone between the tip of the claw member and the corner of the tooth tip of the rotating gear body by high-speed rotation of the rotating gear body, A pulling force can be generated to instantly pull the pinbone from the fillet.

  In addition, by adjusting the pair of left and right holding members in advance to a state corresponding to the depth of compressing both side portions in the width direction of the fillet, the state is positioned downward from the lower peripheral surface of the rotating gear body, The contact pressure of the rotating gear body with respect to the center portion in the width direction of the fillet having the pin bone can be maintained at an ideal constant pressure at which the pin bone can be smoothly pulled out. It is also possible to prevent the fillet portion from being broken or collapsed during extraction.

According to the second aspect of the present invention, the height from the fillet transport surface is spaced above the fillet transport surface of the conveyor that transports the fillet from the front side toward the rear with a constant interval in the width direction of the conveyor. Both vertical frame bodies are arranged so that the height can be adjusted, and a rotary shaft that is rotated by a motor is supported between the lower end portions of the front support frames in these double vertical frame bodies, and the longitudinal center of the rotary shaft is supported. Since the rotating gear body is fixed to the part, the rotating gear body is formed in a short length with respect to the width direction of the conveyor, and is fixed only to the central portion in the length direction of the rotating shaft supported between the lower ends of the front support frame. since the the structure, in the state where the pin bones of fillet is in contact with the rotating gear body only partially present, distribution of the pressing member for pressing the back and abdomen of the fillet on both sides of the rotating wheel member It can be a structure.

In addition, both end portions of the claw member mounting shaft are rotatably supported between the lower end portions of the rear support frames in the both side vertical frame bodies , and obliquely downward toward the front in the central portion in the length direction of the mounting shaft.

A female screw body 23 made of a nut is fixed in the longitudinal direction of one of the links (upper link 21 in FIG. 3) in the longitudinal direction, and the screw threaded through the female screw body 23 The front end of the body 24 is brought into contact with and received by the rear surface of the machine casing a, so that the bolt body 24 Screwing, by causing screw retreat, rotate the parallel links 21, 22 in the vertical direction, and configured to adjust the height to the conveyor 1 on both sides longitudinal frame member 5,5. 25 is a lock nut.

  The conveyor 1 is inclined so that its fillet conveyance surface gradually increases from the conveyance start end side of the fillet F, that is, from the front end side to the lower side of the rotating gear body 4. The drive pulley 1a is rotated via a drive means (not shown) to convey the fillet F toward the rear. Further, the rotating gear body 4 also has one end of the rotating shaft 6 to which the rotating gear body 4 is fixed in the conveying direction of the conveyor 1 via a driving means by a motor (not shown) and the conveying speed of the conveyor 1. It is configured to rotate at a high peripheral speed.

  Next, in order to extract the pin bone B existing in the fillet F in the state of being embedded in the fillet F by the apparatus configured as described above, first, the both side vertical frame bodies 5 and 5 are moved in the vertical direction by rotating the bolt body 24. The height of the rotating gear body 4 from the conveying surface of the conveyor 1 is adjusted so that the rotating gear body 4 contacts the surface of the fillet F with a constant contact pressure, and the front sides of the vertical frame bodies 5 and 5 on both sides The pair of left and right presser members 2 and 2 disposed on the lower end side of the support plate 15 by moving the support plate 15 in the vertical direction with respect to the fixed shaft 14 connected between the support frames 5A and 5A. The horizontal pressing surface 2a is positioned below the lower peripheral surface of the rotating gear body 4 so that both sides in the width direction of the fillet F, that is, the back side and the abdomen side, include both vertical frame bodies 5 and 5. Horizontal pressing of presser members 2 and 2 using the total weight Previously adjusted so as to press by 2a.

  After adjusting in this way, the fillet F before extracting the pin bone B on the central portion in the width direction at the conveyance start end of the conveyor 1 is directed in the longitudinal direction, that is, in the conveyance direction, and the outer skin side It is placed in a state facing the transport surface and transported toward the pin bone extractor. In order to ensure that the pin bone B can be fed to the lower peripheral side of the rotating gear body 4, the rotating gear body 4 is arranged from above at the center of the upper surface of the conveying start end of the conveyor 1 on the front side of the rotating gear body 4. It is projected by irradiating two strips of infrared rays with an interval substantially equal to the width of the fillet F, and the fillet F is placed so that the pinbone B of the fillet F enters the conveyor 1 between these lines.

  Thus, the conveyer 1 conveys the fillet F backward, and the fillet F reaches the pair of left and right holding members 2 and 2 and comes into contact with the inclined surface 2b formed on the lower surface of the front end portion of the holding members 2 and 2. Then, the back and abdomen of the fillet F are pressed and compressed downward by these inclined surfaces 2b, 2b which are gradually inclined downward toward the rear. At this time, the conveying surface of the conveyor 1 is gradually inclined upward toward the lower side of the rotating gear body 4 and travels in parallel with the lower surfaces of the presser members 2 and 2 from the upper end of the inclined portion, as shown in FIG. Thus, both sides of the surface of the fillet F are conveyed backward from the inclined surfaces 2b and 2b of the holding members 2 and 2 in contact with the lower surfaces of the horizontal pressing surfaces 2a and 2a, and are directed in the horizontal direction from the inclined upper end of the conveyor 1. When changing, the fillet F is refracted into a mountain shape, and the tip of the pin bone B, which has been provided in the fillet F until then, stands up from the surface of the fillet F.

  Furthermore, when the fillet F passes in contact with the lower surfaces of the pair of left and right pressing members 2 and 2, both sides thereof, that is, the back and the abdomen are pressed by the load of the entire device acting on the pressing members 2 and 2. The compression force is also transmitted to the fillet portion where the pin bone B exists between them, and the tip of the pin bone B protrudes relatively from the surface of the fillet F according to the compression amount, and this protruding state is maintained. The claw member 3 disposed between the presser members 2 and 2 and the rotary gear body 4 are conveyed.

  When the fillet F is conveyed below the rotating gear body 4, the pinbone B protruding from the fillet F protrudes from the tip of the claw member 3 whose height is adjusted in advance so as to be in light contact with the surface of the fillet F. At the same time as the base end portion comes into contact, the tooth portion 4a on the lower peripheral side of the rotating gear body 4 rotating in the same direction at a speed faster than the conveying speed of the conveyor 1 has a claw member 3 as shown in FIG. The tip end of the pin bone B is housed in the concave groove 4b between the tooth portion 4a and the preceding tooth portion 4a in contact with the tip end of the tooth portion 4a and the tip end of the claw member 3 The protruding proximal end portion of the pin bone B is sandwiched.

  Further, since the claw member 3 has its concave arcuate upper surface 3b elastically contacted with the lower peripheral surface of the rotating gear body 4, the pin bone B is connected to the concave arcuate upper surface 3b of the claw member 3 and the tooth portion of the rotating gear body 4. The pinbone B is instantaneously pulled out from the fillet F along the concave arcuate upper surface 3b of the claw member 3 by the rotational force of the rotating gear body 4 by being sandwiched between the tip surfaces of 4a.

  In this way, a large number of pin bones B existing in a line in the length direction in the fillet F are sequentially extracted by the claw member 3 and the rotating gear body 4, and the extracted pin bones B are extracted from the rotating gear body 4. Due to the rotational centrifugal force, it is separated from the rotating gear body 4 and is received by a pin bone receiving plate 20 disposed on the front side of the rotating gear body 4, and sprayed to the pin bone receiving plate 20 from one side. It is received by a pin bone storage portion disposed on the other side of the machine base A by jet water (not shown).
